Toner cartridge
Photosensitive drum
The photosensitive drum is the heart of the image formation system. This drums special properties
allow an image to form on the drum's surface and then transfer to paper. The drum is an aluminum
cylinder coated with an organic-photoconductive material (OPC). The photosensitive drums
aluminum base is electrically connected to ground. The OPC material becomes electrically
conductive when exposed to light. Areas not exposed to light remain nonconductive and maintain
their negative charge.

Cleaning stage
At the cleaning stage, the photosensitive drum's surface is prepared to hold an image. During
printing, the drum rotates completely several times per printed page. Before forming the image for a
given section of print, a cleaning blade removes toner from the previous rotation of the drum. The
toner cartridge stores waste toner and prevents it from being used in later print jobs.
